UNITED sa rs rarnr QFFICE GEORGE A. KNOBLOCK, OF SOUTH BEND, INDIANA.

SEEDER.

To all whom it may concern:

Be it known that I, GEORGE A. KNoBLocK, a citizen of the United States,residing at South Bend, in the county of St. Joseph and State ofIndiana, have invented certain new and useful Improvements in Seeders,of which the following is a specification.

This invention relates to certain new and useful improvements inseeders.

The invention has for its object the production of an implement of thischaracter by means of which a furrow may be opened, the seed depositedand the furrow closed, all by one mechanism operating in a series ofsuccessive steps.

A further object is to provide improved means for supporting the listerplow.

A further object is to provide means for raising the lister plow into aninoperative position and to simultaneously and automatically throw theseed feeding mechanism out of gear.

A further object is to provide means for automatically disconnecting theseeder mechanism when backing or turning.

The invention will be hereinafter fully set forth and particularlypointed out in the claims.

In the accompanying drawings-Figure 1 is a side elevation of themachine, one wheel being removed. F 2 is a view in front elevation ofthe seeder. Figs. 3 and 4 are detail views showing the mechanism forcontrolling the seed operating devices.

Like characters of reference designate corresponding parts.

Referring to the accompanying drawings, 10 designates a frame composedof side bars and supported at the forward end by a bent or invertedU-shaped axle 11, which in turn is carried by suitable traction wheels12. The rear end is supported by covering wheels 13 hereinafter referredto.

The beam 14 of the lister plow is pivotally supported by clips 15secured to the central portion of axle 11 and the rear portion of saidbeam is pivotally connected at 16 to the contiguous upper ends of links17, the opposite ends of which are supported by ears 18 depending fromframe 10. A lever 18 is arranged to adjust the axle 11 as required.

The seeder box 19 is supported in any suitable manner and provided witha feeder shaft 20 rotated through the medium of a Specification ofLetters Patent.

sprocket chain 21, and sprockets 22-23, the latter being provided with ahub 24 mounted on axle 11. From box 19 leads a flexible tube 25 whichdischarges into a rectangular tube 26 attached to the plow beam 14 andprovided with coverers 27. The hub 28 of wheel 12 is provided withclutch teeth 29 which are adapted to engage similar teeth 30 on hub 24,said hubs being normally held in engagement by a spring 31. If desired,a spacing section 32 may be employed, where by by placing the same toone side or the other of the wheel, the traction wheels may be adjustedfor diflerent widths to conform to the rows.

The hub 24 is provided with a groove 33 to receive the forked end of alever 34 pivoted to frame 10 by an offsetting stud, and terminating atits upper end in a flat, camshaped plate '35 which projects across thepath of one of the vertical legs of axle 11.

The double mold board plow 37 follows a rolling colter 36, andimmediately back thereof are located covering disks 38. The wheels 13are inclined and so arranged that they will pack the earth over thegrain covered by disks 38.

In operation the action of the parts is as follows :Assuming that thefurrow opening devices are dropped into the ground, the colter will cutthe ground, the plow will spread it, and make the furrow into which theseed is dropped in the well known manner, after which the seed iscovered by disks 38 and the loose earth packed down by wheels 13. Whenit is desired to discontinue operations or to transport the implement,the cranked portion of axle 11 is raised, bringing up the forward end ofplow beam 14 and drawing it rearwardly, whereupon the links 17 raise theplowshare and its adjuncts out of the ground, and high enough to clearit. As the vertical part of the crank shaft 11 turns backward, itstrikes the edge of cam plate 35, and forces lever 34 to swing on itspivot, thus withdrawing hub 24 from engagement with hub 28 and throwingthe seeder mechanism out of operation.

From the foregoing description it is evident that in backing up,(because of the inclined teeth of the hubs 24 and 28, and the spring31), that hub 24 will remain idle, allowing the teeth of hub 28 to slidepast. Thus the seeder is automatically rendered inoperative when theplow is not working, either during transportation or in backing up toavoid an obstacle, or in turning.

I claim as my invention 1. A seeder comprising a frame, an in- VertedU-shaped axle mounted therein, traction wheels mounted on the axle,means carried by the axle for supporting a plow, means for adjusting thecranked portion of the axle to raise and lower the plow, aseeddepositing mechanism operable from the axle, a clutch on the axlecontrolling said seed-depositing mechanism, an operating lever pivotedto said frame with its lower end engaging the movable member of theclutch, the upper end of the lever having a transversely extendedflattened portion with a cam face rigid therewith at a right anglethereto and projected across the path of one of the vertical legs ofsaid axle.

2. A seeder comprising a frame, an inverted U-shaped axle mountedtherein, traction wheels mounted on the axle, means carried by the axlefor supporting a plow, means for adjusting the cranked portion of theaxle to raise and lower the plow, a seeddepositing mechanism operablefrom the axle, a clutch on the axle controlling said seed-depositingmechanism, an operating lever pivoted to said frame with its lower endengaging the movable member of the clutch, the upper end of the leverhaving a transversely extended flattened portion with a cam face rigidtherewith at a right angle thereto and projected across the path of oneof the vertical legs of said axle, and means interposed between theframe and the said clutch below the pivot of the lever for normallyholding the clutch in engagement.

3. A seeder comprising a frame, an inverted U-shaped axle mountedtherein, traction wheels mounted on the axle, a beam pivotally supportedby means secured to the central portion of said axle, rearwardly anddownwardly inclined links pivotally connected at their upper ends to therear end of said beam, ears depending from said frame and in which therear ends of said links are pivoted, a lever for adjusting said axle, adouble mold board plow carried by said beam, a rolling colter in frontof said plow, covering disks immediately at the rear of said plow, aclutch mechanism on the axle, a lever pivotally mounted for actuatingthe same, and a horizontal cam-shaped plate carried by the upper end ofsaid lever in the path of one of the vertical legs of the said axlewhereby as the crank axle is raised to draw the forward end of the plowout of the ground said Vertical leg will turn backward and strike theedge of said cam plate to swing said lever on its pivot to actuate theclutch mechanism.

In testimony whereof I aflix my signature, in presence of two witnesses.
